I've always put the gaps between 2 and 4, and 8 and 10 o'clock looking at it from the top with 12 o'clock facing the lifter valley. Top and second at 180* apart. Oil rings 180 apart as well. From instructions I saw long ago, and thinking it will keep the gaps away from the thrust side of the pistons. Seemed to work, but I would not try to out think any guideline provided by the manufacturers.
If the results don't match the theory, change the theory.

From instructions I saw long ago, and thinking it will keep the gaps away from the thrust side of the pistons. Seemed to work, but I would not try to out think any guideline provided by the manufacturers. This is what I basically do with the comp rings 180 apart and the oil ring rails 180 apart. I agree they will move around when the eng runs as you see them all over when you take them apart. Ron
